fix(validation): harden policy scalar trust boundary - #1020

ChangesValidationPolicy scalar safety
Estimated code review effort: 2 (Simple) | ~15 minutes Merge Risk: 🔵 Low · up to The PR narrows accepted policy scalar types to prevent caller callbacks during validation and preserves built-in marshalling behavior. It is otherwise a bounded change, but merge readiness remains low risk until the required exact-head security scan is completed and any HIGH or CRITICAL findings are addressed. Possibly related PRs

Pull request overview
OpenCode cannot approve yet because required coverage evidence did not pass.
Review outcome
1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence
-
Problem: The required coverage-evidence job result was
failure, so OpenCode cannot establish approval sufficiency for this head. -
Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.
-
Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports
successwith required evidence or explicit no-source not-applicable evidence. -
Regression test: Keep the approval branch checking
needs.coverage-evidence.result == successbefore posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present. -
Result: REQUEST_CHANGES

Current-head review for a795405. The historical CodeRabbit NumPy-scalar nit is already implemented in the exact current diff: the parameterized test covers float16/32/64/longdouble and int64 and asserts built-in float Rust marshalling. Focused suite: 15 passed; Ruff, Interrogate 100%, and diff checks pass. The prior OpenCode REQUEST_CHANGES is tied to superseded central coverage-evidence infrastructure; no current source finding remains. Please replace stale review state with fresh exact-head evidence.

Current-head re-review request (a795405): prior OpenCode CHANGES_REQUESTED evidence references an older head or superseded coverage infrastructure. Re-evaluate only this exact SHA and publish fresh coverage/docstring evidence before making a decision. Existing focused local evidence is recorded on the current-head review comment; protected checks remain fail-closed. |

@opencode-agent @cwl-noema-review Re-review the exact current head The prior current-head REQUEST_CHANGES only reported unavailable/failed coverage evidence from an earlier run. Current CI, Security Scan, SAST Semgrep, and CodeQL runs for this exact head are terminal-success. Re-evaluate this head and publish independent approvals only from fresh evidence; do not reuse prior-head reviews. Protected merge policy remains unchanged. |

@opencode-agent Please perform a review-only formal review of exact current PR head |
|
Current-head manual review completed for a795405. The scalar trust-boundary fix is correctly scoped: exact built-in and concrete NumPy real values are normalized without caller conversion hooks; hostile string, float, and integer subclasses are rejected before strip, conversion, or comparison; Rust remains the decision/arithmetic owner. Focused validation passed: 15 callback-safety tests, Ruff, interrogate 100 percent, compileall, and diff check. gh pr checks is green for the current head across CI, GPU, fuzz, package, Rust, security, OpenCode, and Noema. No actionable source defect found; normal merge remains subject to independent formal approval. |

Fresh exact-head re-review requested for a795405. The existing OpenCode CHANGES_REQUESTED reviews are coverage-evidence failures from 2026-08-19; current-head CI, security, Noema, Strix, and coverage evidence are terminal-success. Re-evaluate this unchanged head under the repaired central coverage contract and publish a fresh formal decision. No bypass or self-approval. |

@opencode-agent please re-review — this PR's CHANGES_REQUESTED review appears stale (all current checks pass on this head). This is a score-integrity hardening PR; re-approval would help unblock the fast-mlsirm backlog per ContextualWisdomLab/.github#1212. |

Closes #1017.
Defect
ValidationPolicy.__post_init__admitted caller-definedstr,float, andintsubclasses throughisinstance(...)and then invokedstrip(),float(...), or comparison operators. A hostile policy scalar could therefore execute caller callbacks while semantic controls were still being admitted, before the Rust validation decision owner ran.RED → GREEN

This is Python validation and marshalling only. Williamson thresholds, scoring-validation formulas, pass/fail arithmetic, result interpretation, and all production psychometric computation remain unchanged and Rust-owned.
